Build Your Own DIY Smart Mirror with Arduino and ESP32

A smart mirror is a must-have accessory for tech enthusiasts. It can display the latest news, weather, your calendar, and much more. In this blog post, you will learn how to build a smart mirror with Arduino and ESP32.

Required Components

• Mirror
• Display panel (e.g., Raspberry Pi touchscreen)
• Arduino Mega or ESP32
• Adafruit NeoPixel strip (optional)
• Mirror film
• Power supply
• Speakers (optional)
• Wood or aluminum for the frame

Programming

Arduino Code:

#include <Adafruit_NeoPixel.h>

// NeoPixel settings
#define NUMPIXELS 60
#define PIN 6
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  pixels.begin();
}

void loop() {
  // Control light effects here
  pixels.clear();
  pixels.setPixelColor(0, pixels.Color(255, 0, 0));
  pixels.show();
}

ESP32 Code:

#include <WiFi.h>
#include <HTTPClient.h>
#include <ArduinoJson.h>

// WiFi settings
const char* ssid = "your_ssid";
const char* password = "your_password";

void setup() {
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
  }
}

void loop() {
  // Fetch news
  HTTPClient client;
  client.begin("https://newsapi.org/v2/top-headlines?country=us");
  int statusCode = client.GET();

  if (statusCode == 200) {
    String response = client.getString();

    // Parse JSON
    DynamicJsonDocument doc(1024);
    deserializeJson(doc, response);

    String title = doc["articles"][0]["title"];
    String description = doc["articles"][0]["description"];

    // Display news on screen
    Serial.println(title);
    Serial.println(description);
  }

  client.end();
}

Assembly

1. Prepare the mirror: Cut the mirror film to the size of the mirror and apply it to the back.
2. Mount the display: Attach the display panel to the mirror using adhesive or screws.
3. Install Arduino/ESP32: Mount the Arduino or ESP32 behind the mirror.
4. Connect the components: Connect the display, NeoPixels (optional), and speaker (optional) to the Arduino or ESP32.
5. Assemble the frame: Build a frame using wood or aluminum and attach it around the mirror.
6. Add extra features: You can add more features, such as voice control or gesture recognition, using additional components or a smartphone app.

Conclusion

A DIY smart mirror with Arduino and ESP32 is a versatile and fun project that provides you with a unique accessory. With some skills and patience, you can create an intelligent mirror that will enhance your daily routine.
